SPINDLE AND BOBBIN ()li RING-SPINNING AND RING-DO UBLING FRAMES AND THE LIKE.

Specification of Letters Patent. Patented Dec. 30, 1919.

Application filed March 26, 1919. Serial No. 285,367.

- To all cohom it may concern The invention relates to the spindles and bobbinsof ring spinning and ring doubling.

" frames and the like, and has for object the provision of simple and effective means therewith whereby an increasein the speed oifsaid spinning or twisting, and an increase in the amountor length ofyarn spun and wound upon the cop or bobbin maybe attained. 'Such' means enable the cops of yarn orthrea'dto -be formed on the bare spindle, or upon a smaller tube than the diameter of the ordinary bobbin, and with 1 the useof the ordinary traveler and spinthechase is'relieved by reason of the pull i of the yarn at the traveler being more nearly l ningring.

[and ring doubling according to the means It is well known that in ring spinning hitherto adopted, thereisa variation in the ning at the shoulder or large diameter of -tangential to the ring than at other times. w The conical shape of the cop however necessitates a movement of the ring rail as will result in succeeding layers of yarn being wound on from the base of the cone or chase to the nose, or vice versa as is understood, so

thatasthe nose of the cop is approached,

r thepull upon the yarn becomes less tangential' to the ring, with a corresponding grad- 11:11 increase in the tension'or drag upon said yarn,until the"nose is reached, after'which 'the tension gradually decreases as spinning and'winding proceed toward the larger dij ameter'aga'in,

In order to minimizethis' difliculty ofincreased tension as described, a common practice isto usefairly large diameters for the or other suitable substance, which is capable of being passed about or on to a spindle or bobbin or tube, and of being moved up the same, by the action of the yarn, as the building of the cop or bobbin proceeds.

The yarn travels over or about the edge or periphery of said member before it passes to the ordinary traveler on the spinning ring. By this means, the diametrical distance from the axis of the spindle to the point at which the yarn touches the memher or so passes over' the edge (when the yarnis not ballooning) is a constant or approximately so, at all heights during the building up process under the conditions referred to. The eifec't of this is that, the yarn and, with it, the traveler are carried aroundgincreased tension of-the yarn which would occur in ordinary circumstances, being obviated.

Increased. speedof spinning, with fewer broken endsithus becomes possible. Added to which, the employment. of the member referred to, enables spinning to be accomplished upon a thinner bobbin or pirn than usual, or even upon the bare spindle itself,

giving increased amount or length of spun material wound upon the same.

Withreference to the accompanying drawings, Figure lshows' a member or deviceaccording to one form of my invention, and Fig. 2 shows a cop spindle and adjacent parts, in'sectional elevation, with the said 'member' in posltlon thereon; .Fig. 3 shows some portion of Fig. 2, with a part of a cop formed thereon, and Fig. 4; is a similar view with the cop about built up completely.

Fig. 5 is a modified member or device, and Fig. 6 is a form of spindle suitable therefor.

' traveler mounted thereon;

Fig. 7 shows a bobbin spindleprovided with a paper or other bobbin of comparatively small diameter.

Fig. 8 shows a member or device in position for being doifed off the spindle by a clip arrangement indicated.

With reference to Figs. 1 to l inclusive, u is the cop spindle provided with the usual wherve b for being drivenfrom the tin roller on the f 'ame. c is the ring, and (Z the c is the ring rail movable in a vertical direction, by the usual poker methods, for enabling the cop to be properly. built up.

it is the yarn to be spun and wound upon the spindle a to form the cop. z' is a member with a rough edge or according to one form provided with ratchet like teeth, regularly or irregularly spaced apart at its periphery, and having a hole j therein to enable the do- I vice or member to be passed on to and down the spindle a. The member 2' is shown provided with a preferably dished portion i in this instance, for the purpose to be named "hereafter. At the commencement of spinning operations on a bare spindle, I prefer to make use of a paper tube, of any suitable form and diameter, such as at 70, for supporting the member 2' until such time it can be supported by the wound on yarn. I prefer that the diameter of the member 2' be a mean between the inner and outer diameters of the rmg 0, but other dimensions of the member 2', whether greater or less than indicated, may be employed.

*' In Fig. 3 the cop is shown partly built up succeeding layers of wound on yarn, according to the operation of the ring rail 6 of Fig; 1, which cop portion at its upper end sup'ports, turns and lifts the member i as said cop P01131011 develops.

But frictional con- 'tact' with spindle'a may help to turn memfori'riing the portion of the cop shown is her 2'.

At the position shown in said Fig. 8, the

ing of the yarn away from the spindlea and the member 2'. To enable this to be possible, the yarn? must be quite free from any restraining influence between the traveler l and the usual guideor curl (not shown) above the spindle point. In this sense the yarn may be referred toas being unrestrained.

"At such time, the'oflice of member 71 is not required to-be performed, but as the-yarn nearer tothe spindle a at the upper part of said cop portion, the tension during wind 1 ing at that partmight'be sufficient to reduce, 60

the ballooning so that the yarn h bore agaiiistthe edge of the rotating member 21. A similar condition isshown in Fig. a, where the-tension near the nose portion" of the cop being formed is considerable, comparatively speaking. It will be seen that while ever in contact with the member 2', the yarn h is kept thereby at a constant distance from the spindle a and is being carried around by said member, thus preventing the yarn from the usual thread guide taking a direction or angle such as indicated by broken line in Fig. 4 aforesaid.

When using toothed projections for the member 2' as in Fig. 1 for arrying around or rotating the yarn, I may arrange the member z' in position on the spindle so that it turns in the negative direction as regards said teeth. This is to facilitate the sliding off of the yarn from the teeth when ballooning occurs.

Means maybe provided for keeping the edge portions of the member 71 clear of the ringer traveler as the same approaches the member during spinning and winding. Said means here illustrated consist of the dished part i By reversing the member, so that its upper side shown is made the underside, it becomes suitable for being turned in the opposite direction. In such case it could be providedwith a projecting part" or parts on that reverse side for fulfilling the office of dished part '5 Or it could be flat if desired.

Means may be provided for enabling the member 2' to be driven positively by the spindle a, as an-example in Fig. 5 memberc, with a central aperturev 7', and projecting parts 2' is shown, the'latter' being. capable of engaging grooves in or beingrin gear with a spindleu, one of said grooves being indicated at a in Fig. 6. These grooves would be deeper toward the lower. end of the spindle, so that on the memberibeing mounted on the spindle a,-the projections i would always prevent the upper part of sumed as shown.

In said Fig. 5'the edge of the member 71 is shown differently provided tothe case of Fig. 1, or the edge is capable of being engaged by the yarn but will allow said yarn to slip away when and as described.

In Fig. 7, Z is an ordinary form of bobbin spindle,which I may supplywith a=paper or other "bobbin 'm, having by preference parallel sides down to the swelled portion, and of comparatively small diameter at said parallel part. The member z'therefor, would have a central aperture'to suit. The bobbin could begroovedas in the-case of the spindle a in Fig. 6 if desired, and the member i constructed to engage same.

In Fig. 8, a member of similar form to the one shown in Fig. 1, is assumed to be one 0 of many mountedv on respective'spindles a, and at the period when the cops are completed and doffing of the members i desired.

A board 41, provided with gaps such as 0 (one for each spindle operated upon) is capable of being pushed toward the spindles a or toward the bobbins, so that each gap 0 may engage a part of each member 2', for example, a projecting boss 2' below and about the aperture 7', and indicated in broken lines in the figure.

By the sliding of the board under a number of members forming a section of the total, the same may be dotted or lifted off the spindles at one operation. And for retaining them in position. on the board m, ready to be dropped on to the spindles again, spring devices such as spring clips p on the under side of said board a may be provided.

In the case of Fig. 5 and Fig. 6 the member 2' would be posltively carr ed around by the spindle a, but in other cases where no direct connection between the spindle and the member exists, the latter would be carried around by frictional contact with the top of the nose of the cop or the like on which it rested or was supported thereby,

or by whatever support was provided for it in this manner.

In some cases the members i may be dofied singly. The spindle, bobbin, or tube upon which the spun yarn is wound, may be termed a yarn container.

I claim 1. In ring spinning and ring doubling frames and the like, in which the yarn is unrestrained, a horizontally situated yarnrotating member passing about a yarn container, and riding upon the top part of the wound on yarn, said member provided with a serrated verticaledge, for the purpose and in manner substantially as herein set forth.

2. In ring spinning and ring doubling frames and the like, a horizontally situated yarn-rotating member in the form of a disk, passing about a yarn container, said member in frictional contact with the top part of the wound on yarn, and said member provided with a serrated vertical edge in the form of ratchet-like teeth, for the purpose and in manner substantially as herein set forth.

In testimony whereof I have atfiXed my signature.

JOHN HENRY BUCKLEY.
